Which three values make up the combination for Ease calculation in AWPP path selection? (Choose three.)
The correct answer is A. coefficient based on SNR E. hop value F. SNR. AWPP calculates an 'Ease' metric using the raw SNR, an SNR-derived coefficient, and a hop value penalty to determine the optimal backhaul path to the root AP.

Why each option
AWPP calculates an 'Ease' metric using the raw SNR, an SNR-derived coefficient, and a hop value penalty to determine the optimal backhaul path to the root AP.
A coefficient based on SNR is a normalized multiplier derived from the measured SNR between two mesh nodes and is a direct arithmetic input into the AWPP Ease formula, scaling the quality component of the metric.
Link budget is a general RF engineering planning tool used to verify theoretical path feasibility but is not one of the discrete inputs in the AWPP Ease formula used during runtime path selection.
Rx sensitivity is a fixed hardware specification describing the minimum detectable signal power of a radio and is not a dynamic variable factored into the AWPP Ease calculation.
Antenna gain is a physical hardware characteristic used in link budget design calculations but is not a separate component included in the AWPP Ease metric formula.
The hop value represents the number of hops required to reach the root AP and is subtracted from the SNR-based component in the Ease formula - paths with more hops receive a lower Ease score, biasing selection toward shorter routes.
The raw SNR value between adjacent mesh nodes is the foundational RF link quality measurement that drives the Ease calculation, reflecting actual link conditions between a MAP and its upstream neighbor.
